Crushed LimestoneFirstly there is gravel, crushed rock, pebble, etc. Most would advice against and lose rock base as it very difficult to maintain for a few reasons:

Spreads onto adjacent landscaping and grass

Weeds eventually grow through

Tracks dust, and dirt into the garage

Pavers BlockSome love the look of pavers block. You can count on it being more expensive then concrete. It can last a lot longer (think about some the cobble stone streets that are hundreds of years old) but it’s only as good as its foundation. Extreme weather will cause more shifting (wet and dry spouts will cause the foundation to shift).

As you can see, if you are building out back and want to maintain that green look you have a lot of options. If maintaining that grassy look isn’t your number one priority Pavers Block or Acid Stained concrete can look unreal!

I have a long driveway to my detached garage. I restore vintage motorcycles, so I need a surface that packed down well since asphalt and concrete would be too expensive right now. I had 100 tons of crush and run laid down for around $1600. It has packed down really well, drainage is good, and I can ride on it with the motorcycles although you can’t be stupid and treat it like it’s a hard surface.
